ABSTRACT:
A multi-product sampling mechanism (10) having a clean valve (36), a sample cabinet (40) connected to the clean valve (36), and a utility cabinet (12) connected to the clean valve (36) and the sample cabinet (40) for controlling and cleaning the operation of the clean valve (36) and the sample cabinet (40). In a preferred embodiment, the sample cabinet (40) includes connection blanks (80) for the connection of additional sample cabinets (40) so that, if desired, more than one particular type of product or chemical can be received exclusively at a designated sample cabinet (40). Additionally, in a preferred embodiment, the clean valve (36) is connected a spacer connection (32) for connecting the clean valve (36) to a bulk-storage tank at the receiving facility. The spacer connection (32) is also connected to the utility cabinet (12). By means of the use of connecting tubing (16), cleansing fluid such as ultra-pure water is utilized to operate a spray gun (30) and inert gas such as nitrogen is utilized to operate the pneumatic valves, as well as for use of UPW followed by nitrogen gas to purge the connection tubing (16). As a result, the multi-product sampler (10) is capable of being automatically cleaned and ready for receipt of product after use. Further, the collection of a chemical sample is accomplished in a safe, sealed area and cleansing fluids and gases and chemicals flushed or spilled are directed to appropriate environmentally sensitive industrial waste or drum recovery facilities.
